The device that collection engine test machine oil sampling of the present invention is measured with oil temperature, including temperature sensor,
Before oil discharge screw, seal plug, the first teflon pipe and the second teflon pipe, the first teflon pipe rear end and the second teflon pipe
End is connected by snap joint, and the second teflon pipe rear end is connected with oil discharge screw, the first teflon pipe, the second teflon pipe and
Oil discharge screw offers centre bore, and each centre bore is interconnected and forms temperature sensor via, and temperature sensor is located at described
In temperature sensor via, the thermometric end of temperature sensor is passed from the centre bore of oil discharge screw, temperature sensor it is another
End is located at the first teflon pipe front-end port, and interference fit at seal plug and the first teflon pipe front-end port is realized close
The positioning of envelope and temperature sensor.
Further, the second teflon pipe rear end is attached with oil discharge screw by pressure sensor seat base and block,
The rear end of pressure sensor seat base is provided with external screw thread, and oil discharge screw centre bore front end is provided with the internal thread for matching, pressure
Force snesor seat base is threadedly coupled with oil discharge screw, and the front end of pressure sensor seat base is provided with installation portion, installation position
In in the second teflon pipe rear end, block spins with pressure sensor seat base middle part, by the second teflon pipe rear end and peace
It is fixed at the cooperation of dress portion.
Further, the snap joint includes joint body, the gear ring being arranged in joint body and is arranged on joint sheet
The switch at body two ends, switchs the expansion and contraction for controlling gear ring.
The device that collection engine test machine oil sampling of the present invention is measured with oil temperature, due to above-mentioned knot
Structure, can adjust temperature sensor length to appropriate measurement position, reuse seal plug sealing and fixed, convenient regulation temperature
Degree sensor stretches into measurement position, reduces measurement error, is normally used and examination beneficial to dipstick.When needing machine oil sampling,
Only the first teflon pipe need to be made to be separated with the second teflon pipe by snap joint, engine motor oil can from the second teflon pipe
Central hole outflow, reuse sampling bottle sampling, sampling completion, by snap joint by the first teflon pipe and second
Teflon pipe is connected, you can is continued measurement and is used, the easy to operate and quick and safe.

Specific embodiment
In order to technical scheme is explained further, come that the present invention will be described in detail below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1 to Fig. 5, the device of the collection engine test machine oil sampling and oil temperature measurement, including temperature
Degree sensor 1, oil discharge screw 7, seal plug 2, the first teflon pipe 3 and the second teflon pipe 8.The rear end of first teflon pipe 3
It is connected by snap joint 4 with the front end of the second teflon pipe 8, snap joint 4 includes joint body 42, is arranged on joint body 42
Interior gear ring 43 and the switch 41 at the two ends of joint body 42 is arranged on, switch 41 is used to realize the expansion and contraction of gear ring 43.The
The rear end of two teflon pipe 8 is attached with oil discharge screw 7 by pressure sensor seat base 5 and block 6, pressure sensor seat bottom
The rear end of seat 5 is provided with external screw thread 53, and the centre bore front end of oil discharge screw 7 is provided with the internal thread for matching, pressure sensor seat
